I know there are always many other factors involved but lets filter those out for the sake of this potential example

Horse A runs about a zero every time. Horse A does loom the lone speed and drew inside.
Horse B runs about a zero every time. Horse B drew just outside Horse A and has stalking speed if he chooses.

Horse B is giving Horse A 5 lbs or 1 point in figures.
Horse A is even money
Horse B is 8-5
The rest of the field has no chance.
I played Horse B on Saturday because I was willing to give the 5 lbs for the value. Was I wrong?
